Summaries for SLC4A4 Gene

Entrez Gene Summary for SLC4A4 Gene

  • This gene encodes a sodium bicarbonate cotransporter (NBC) involved in the regulation of bicarbonate secretion and absorption and intracellular pH. Mutations in this gene are associated with proximal renal tubular acidosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

GeneCards Summary for SLC4A4 Gene

SLC4A4 (Solute Carrier Family 4 Member 4) is a Protein Coding gene. Diseases associated with SLC4A4 include renal tubular acidosis, proximal, with ocular abnormalities and autosomal recessive proximal renal tubular acidosis. Among its related pathways are Bile secretion and Pancreatic secretion. GO annotations related to this gene include transporter activity and anion transmembrane transporter activity. An important paralog of this gene is SLC4A8.

UniProtKB/Swiss-Prot for SLC4A4 Gene

  • Electrogenic sodium/bicarbonate cotransporter with a Na(+):HCO3(-) stoichiometry varying from 1:2 to 1:3. May regulate bicarbonate influx/efflux at the basolateral membrane of cells and regulate intracellular pH.

  • Isoform 2: May have a higher activity than isoform 1.

    • Interacts with CA2/carbonic anhydrase 2 and CA4/carbonic anhydrase 4 which may regulate transporter activity (PubMed:12411514, PubMed:14567693, PubMed:15218065, PubMed:15563508). Isoform 1 but not isoform 2 interacts with AHCYL1 (via PEST domain when phosphorylated); the interaction increases SLC4A4 isoform 1 activity (PubMed:16769890). Interacts with AHCYL2 (By similarity).

Post-translational modifications for SLC4A4 Gene

  • N-glycosylation is not necessary for the transporter basic functions.
  • Phosphorylation of Ser-1026 by PKA increases the binding of CA2 and changes the Na(+):HCO3(-) stoichiometry of the transporter from 3:1 to 2:1. Phosphorylated in presence of STK39 and dephosphorylated in presence of PP1 phosphatase; phosphorylation seems to inhibit SLC4A4 activity.
  • Glycosylation at Asn 641 and Asn 661
